Fenix WT26RM Rechargeable Work Light - 2500 Lumens

Performance Highlights

• Spotlight: up to 2500 lumens and a 362 m (1,188 ft) max beam distance
• Floodlight: up to 600 lumens with a high-CRI (≥90) LED for accurate color rendering on-site
• Red light: low-glare constant-on and flash modes for night work or signaling
• Durability: 1-meter impact resistance and an IP66 waterproof rating for real jobsite conditions

Full mode-by-mode output, runtime, distance, and intensity figures are shown in the specifications chart above.

Key Features

• High-performance SFT42R LED (50,000-hour lifespan) for spotlight; high-CRI (≥90) XP-L2 LED for floodlight
• Triple light source: cool white (6500K) spotlight, warm white (5000K) high-CRI floodlight, and red light
• Rotary switch selects Lockout / Spotlight / Floodlight / Red light; electronic switch cycles brightness within each mode
• Intelligent memory circuit recalls the last-used output level per mode (excluding red light)
• Intelligent overheat protection steps down output at 60°C/140°F and restores it once cooled, so it keeps working through a full shift
• Low-voltage warning with automatic downshift, plus a red-flashing battery indicator at critically low charge
• 360° rotatable magnetic mount with hook for completely hands-free use

Battery & Charging

• Included: ARB-L21-5000 V2.0 rechargeable battery (21700, 3.7V) — user-replaceable
• Charging: inner waterproof USB Type-C port, ~3.5 hours from depleted to full with a 5V/2A adapter
• Only 21700 Li-ion rechargeable batteries are supported — AAA Ni-MH, alkaline, and non-rechargeable lithium batteries are not compatible

Size & Weight

• Dimensions: 4.80" x 2.20" x 1.57" / 122 x 56 x 40 mm (including mount)
• Weight: 8.50 oz / 241 g (including battery)

Q: What is "CRI" and why is it important?

A: CRI = "color retention index." A low CRI (under 80) makes colors look washed out, dull, or grayish. A high CRI (90 or above) makes colors appear vibrant, rich, and realistic.

Q: What kind of LED is used in the WT26RM? Does Fenix offer to replace the LED?

A: It's equipped with one SFT42R LED (50,000-hour lifespan) for spotlight, and one XP-L2 LED with high CRI (≥90) for floodlight. Fenix does not currently offer LED replacement service, and independently replacing the LEDs is not recommended, as it may affect performance or damage the light.

Q: What is the color temperature of the WT26RM?

A: Spotlight is 6500K (cool white); floodlight is 5000K (warm white, high-CRI).

Q: What is the working voltage of the WT26RM?

A: Operating voltage range is 3.0V-4.2V; limiting voltage range is 2.8V-4.2V.

Q: Is the WT26RM rechargeable? How long does it take to charge?

A: Yes. It charges via an inner waterproof USB Type-C port in about 3.5 hours from depleted to full with a 5V/2A adapter.

Q: How do I prevent the WT26RM from turning on accidentally?

A: Rotate the rotary switch to the Lockout position to turn off and lock the light, or loosen the battery cover a few turns to prevent accidental activation.

Q: Why does the WT26RM downshift to a lower mode and stop letting me select a higher one?

A: This is by design and has two causes: Intelligent Overheat Protection steps the light down when it reaches 60°C/140°F and restores the mode once it cools; Low-Voltage Downshift steps the light down as the battery depletes until only the lowest output remains available.

Q: Why does the WT26RM flicker?

A: Flickering, intermittent light, or failure to illuminate is usually caused by a low battery (recharge or replace it) or dirty contact points (clean the battery and flashlight contacts with a cotton swab soaked in rubbing alcohol). Contact your authorized distributor if this doesn't resolve it.

Q: What battery should I use in the WT26RM?

A: A Fenix ARB-L21 series battery is recommended; the included ARB-L21-5000 V2.0 is the only battery the charging, battery-level-indicator, and low-voltage-warning features are designed around.

Q: Is the WT26RM still waterproof if the anti-dust cover is left open?

A: Yes — the USB Type-C port has an inner waterproof design. Even so, keep the anti-dust cover securely closed during normal use.

Q: What should I do if the WT26RM needs repair?

A: Fenix offers a 15-day replacement for documented manufacturing defects, 5-year free repair for normal-use issues (2 years for non-detachable light components, 1 year for the rechargeable battery and other accessories), and paid lifetime maintenance after 5 years. Keep your warranty card and contact your authorized distributor for service, or visit fenixlight.com for details.

Overview

The Fenix WT26RM is a high-CRI, dual-source spot-and-flood work light for maintenance, industrial, automotive, and utility work.

Operating Instructions

On: rotate the rotary switch clockwise from Lockout to any mode, or (when unlocked) press and hold the electronic switch for 0.5 seconds.

Off: rotate the rotary switch counterclockwise back to Lockout, or press and hold the electronic switch for 0.5 seconds.

Mode switching: the rotary switch cycles Lockout ↔ Spotlight ↔ Floodlight ↔ Red light.

Output selection: in Spotlight, single-click the electronic switch to cycle Low → Med → High → Turbo; in Floodlight, Low → Med → High; in Red light, single-click to toggle Constant-on / Flash.

An intelligent memory circuit recalls the last output level used in each mode (excluding red light).

Battery, Charging & Level Indication

• Only 21700 Li-ion rechargeable batteries (3.7V) are supported — AAA Ni-MH, alkaline, and non-rechargeable lithium batteries are not compatible.
• Replacement: unscrew the bottom battery cover, insert the battery anode (+) toward the light head, and screw the cover back on.
• Charging: open the anti-dust plug to access the inner USB Type-C port; one indicator flashes green while charging and all five glow steady when complete. About 3.5 hours from depleted to full with a 5V/2A adapter. Works only with Fenix ARB-L21 series batteries.
• Level check: with the light off, single-click the electronic switch — 5 lights = 100-80%, 4 = 80-60%, 3 = 60-40%, 2 = 40-20%, 1 light or red flashing (6Hz) = 20-1%. Works only with Fenix ARB-L21 series batteries.

Protection Features

• Intelligent Overheat Protection: steps down output automatically at 60°C/140°F and restores the preset level once the light cools below that threshold.
• Low-Voltage Warning: downshifts brightness as the battery depletes; once Low output is reached, a battery indicator blinks red to signal it's time to recharge or replace the battery. Works only with Fenix ARB-L21 series batteries.

Usage & Maintenance

• Do not disassemble the sealed head — this damages the light and voids the warranty.
• Fully charge before storage; remove the battery if the light won't be used for an extended period, to avoid damage from electrolyte leakage.
• Lock the light or remove the battery during storage or transport to prevent accidental activation.
• Replace the O-ring if worn, to maintain the waterproof seal.
• Clean battery contacts periodically with a cotton swab and rubbing alcohol if the light flickers or won't illuminate; if that doesn't help, contact your authorized distributor.
